Abstract:
A system for remote control of operation control elements that are arranged in a well to control recovery of gas and/or oil from the well. A first system part is located outside the well and connected to a second system part that is located in the well and operatively connected to the operation control elements. All semiconductor components are housed in the first system part. The second system part houses electromechanical components that actuate the operation control elements upon command from the first system part. A method for remote control of down-hole operation control elements in an oil and/or a gas well completion. A first system part located outside the well is equipped with all semiconductor components that are included in the system. A second down-hole system part is equipped with electromechanical components that are actuated from the first system part for actuation of the operation control elements.
